All Wikicities are able to use the [[MediaWiki]] '''math''' extension to add mathematical formulae to articles.

MediaWiki uses [[Wikipedia:TeX|TeX]] markup for mathematical formulae. T<sub><big>E</big></sub>X, or TeX, is a typesetting system which has largely displaced Unix troff, the other favored formatter, in many Unix installations. TeX generates either PNG images or simple HTML markup, depending on [[Special:Preferences|your preferences]] and the complexity of the expression.

Math markup goes inside NaodW29-nowiki434d6ac33a450d1e00000001 tags.

See [[MetaWikipedia:Help:Formula]] for details on how to use this feature.
